PATENT ANTONIO ALITTO, 'OF CHICAGO, ILLINOIS.

DOOR FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 616,281, dated December 20, 1898.

Application filed May 12, 1898. Serial No. 680,508- .NO odem I To all whom it Duty concern:

Be itknown that I, ANTONIO ALITTO, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Doors for Stoves, of which the following is a specification.

My invention has for its object the provision of a double door for stoves, which when closed shall form an air-jacket between the fire-box or other receptacle and the external air and when open shall afford a shelf for any suitable purposeas, forinstance, to intercept coal or ashes falling from the stove or from the feeding hod or shovel; and it con-' sists in combining with an outer door or doors opening upon vertical hinges an inner door opening upon a horizontal underlying hinge and connecting means whereby the inner and outer doors are simultaneously closed.

It consists, further, in various other combinations and details of construction hereinafter described and claimed.

In the drawings, Figure 1 is a front elevation of so much of the fire-box of a stove with my invention applied thereto as is necessary to the explanation thereof. Fig. 2 is a fragmentary side elevation showing in dotted lines the position of the double doors when open; and Fig. 8, a top plan view, partly in section, with the covering-plate removed.

A is a plate bounded by an insetting angle-iron a to set it out from the stove to give clearance for the pivot rod or shaft of the inner door below described. This plate is secured to the face of the stove over the opening to the fire-box by means of screws a, so as to be readily detachable, and has a doorway a registering with said opening. This doorway is closed by the outer doors B, mounted upon vertical hinges b, so as to open and shut as ordinary swinging doors. Angleirons b on the detachable plate adjacent to the hinges serve as stops to limit the outward movement of these doors.

The inner door 0 is attached by its base to mensions as to close the opening into the fireopened and box or other receptacle and is brought by its hinge into suitable proximity thereto, the doorway through the detachable plate being prolonged to meet and connect with the doorway into the fire-box by means of the hood 0, within which said inner door closes. The

pivot-rod of the inner door extends to the exterior of the stove or range and is provided with a crank-arm .0 which reaches alongside the end thereof and carries a knob c", the

shank of which passes through a curved slot cl in a plate D capping the side of the doorchamber and the said crank-arm, the ends 61' and d of the curved slot form stops to determi'ne the position of the inner door, the

. and hold said outer doors closed.

To open the doors, the pivot-rod of the inner door is rocked by lifting its controllingknob until it strikes the stop (1, thereby turning the rock-shaft or pivot-rod and swinging the door outward and downward until stayed in the position shown in dotted lines in Fig. 2 or in such other position as may be determined by the location of the stop. As said inner door swings outward it rides off of the arms or cams E and strikes the outer doors, throwing them open and against their stops. In closing the doors the action is reversed. The controlling-knob is depressed until it strikes the stop d swinging up the inner door in its movement, and thisdoor, just before entirely closing, engages the arms or cams E and by its action on them closes the outer doors automatically and locks them shut.

I do not limit myself to the specific construction herein described; but

What I claim, and desire to secure by Letters Patent, is

1. In combination with an outer door or doors opening upon vertical hinges, an inner door opening upon a horizontal underlying hinge and forming a shelf when open, and with the outer doors an air jacket when closed, and connecting means whereby the inner and outer doors are simultaneously opened and closed.

2. In combination with an outer door or doors opening upon vertical hinges, an inner door opening upon a horizontal underlying hinge and forming a shelf when open, and insetting arms or cams upon the outer doors, adjacent to their hinges, arranged to engage the lateral edges of the inner door as it closes, to close and lock the outer doors.

In combination with an outer door or doors opening upon vertical hinges, an inner door mounted upon an underlying pivot-rod, a crank-arm upon said pivot-rod exterior to the stove, stops between which said crankarm plays, to limit the opening and closing movement of the inner door, and insetting arms or cams upon the outer doors, arranged to engage the lateral edges of the inner door as it closes, to close and lock the outer doors.

4. In combination with an outer door or doors opening upon vertical hinges, an inner door swinging upon a horizontal underlying hinge, stops to limit the opening movement of the outer doors, stops to limit the opening and closing movement of the inner door, arms or cams insetting from the outer doors to engage the lateral edges of the inner door, and

means for swinging said inner door upon its hinge.

5. The combination with the stove, of the detachable plate having peripheral angleiron, the two outer doors opening on vertical hinges and closing a doorway in said plate, the horizontal rock-shaft or pivot-rod mounted in hearings on the inner side of said plate along the foot of the doorway therethrough, and the inner door attached by its base to said rock-shaft and closing a doorway in the stove, the cams on the outer doors, and means for rocking the shaft.

6. The combination with the stove and with the doorway into the fire-box,of the detachable plate having peripheral angle-iron, and a doorway prolonged bya hood to connect with the doorway into the fire-box, the two outer doors opening on vertical hinges and closing the doorway in said plate the inner door mounted at its base upon a horizontal rockshaft and closing within said hood to shut the doorway to the fire-box, and the cams upon the outer doors with which said inner door engages.

I11 testimony whereof I affix my signature in presence of two witnesses.

ANTONIO AILITTO.
